PORTABLE CHLORIN-DISPENSER.

Specification of Letters Patent.

Patented Dec. 27, 1921.

Application led April 11, 1921. Serial No. 460,523.

To all whom it may concern:

Be it known that I, JAMES W. VAN METER, a citizen of the United Statesof America, residing at 2755 Clay street, city of San Francisco, in thecounty of San Francisco and State of California, have invented certainnew and useful Improvements in Porta.- ble Chlorin-Dispensers, of whichthe followinv is a specification.

lhe present invention is an improved portable chlorin dispenser. Thisapplication re* I lates to the same subj ect matter as my application ofeven date, Serial No. 460,522.

The primary object of the invention is to provide a compact andconvenient apparatus for discharging liquid chlorin lfrom relativelysinall pressure cylinders, for use in furnigation, animal and insectextermination, and other operations in which liquid chlorin is used.

Another object of the invention is to p ro vide in a portable apparatusfor dispensing chlorin, a convenient gage wherein the escape of chlorinmay be visibly controlled and the dispensing accomplished with thegreatest possible accuracy.

.Another object is to provide an apparatus of relatively few arts and ofeconomical structure, which will engage typical chlorin cylinders andsupport the saine in loose ground for use in orchard or farm operations.

In this specification and the annexed draw ings, the invention isillustrated in the forni considered to be the best, but it is to beunderstood that the invention is not limited to such form, because itmay be embodied in other forms, and it is also to be understood that inand by the claims following the description it is desired to cover theinvention in whatever form it may be embodied. h

Referring to the accompanying 1 sheet oi drawings;

Figure l is a vertical side elevation of my device.

Fig. 2 is an enlarged section of the gage portion of Fig. 1.

Fig. 3 is a section on the line III-III of Fi 1, with the chlorincylinder removed.

.eferring to the drawings, Fig. 1, the numeral l indicates a U-shapedrod which constitutes a frame for a chlorin cylinder 2, the uppertransverse portion 3 forming a convenient handle. In bending the rod tothe U-shape shown in Fi 1, the Aends of the rod are converged slight yto form a spring or frictional engagement with the sliding yoke members4 and 6. The yoke member 6 is shown in Fig. 3 in plan view. It iscircular in forni and provided with lugs 7 and 8 on which are bosses 9and 11. These bosses are bored to form a sliding lit with the ends ofthe rod l.

A ange 12 is provided on the yoke 6 over which a depending flange on thebase of the cylinder fits snugly to secure the cylinder againstaccidental displacement. On that type of cylinder which is round invertical cross section, the bottom of the cylinder is engaged bythecircular opening 13 in the yoke 6. l

The yoke l is of similar construction. vThe central bore 13 beingsmaller, engages the reduced neck 1liof the container 2. The eX- ytiernities of the rod 1 are threaded. as shown to be forced into theground by the weight of the device when it is dropped forcibly, and thussupport the entire structure.

I provide a swinging gage 18 which has a limited rotary movement on theleg of the frame 1, which extends through apertures 19 in lugs 21, Fig.Q, and is freely slidable on the said leg and provided with a rubberwasher or cushion 2Q which serves to check the impact of the metal partsas the device is dropped forcibly to the ground.

The gage 18 is preferably a metal casting, closed at the bottom andcapped at the top by a cap 23, having a depending flange 2i, which issecured to the shell of the gage 18 by a set screw 2G.

The inner parts of the gage 18 are of glass and in order yto forni afluid tight seal and to protect the glass parts from impact with metalparte, l provide a rubber buffer 27 which rests upon a disk 28 which ispressed upwardly by a threaded screw 29, extending through the base frombelow and secured in any desired place by a lock nut 31.

A glass tube 32 rests on the buffer 27 and is plugged at the top by arubber cork 33.

'It will be seen that as the parts are assembled, the glass tube isinserted with the rubber plug in place at the top. The 'cap 23 isapplied to the gage 18 and secured by the set screw Q6. By turning thescrew 29 the glass tube 32 is securely held between the. rubber cork 33which abuts the cap 23 and the buffer 27. The rubber cork 33 has acentral bore in which is forcibly fitted sie an inner tube 34, whichterminates in an enlarged bell portion 36, open at the bottom asindicated at 37, and graduated as indicated at 38. This portion 36 isprovided with a. plurality ot' aperatures 39, to permit the escape ofchlorin fromthe tube 34 to the interior of the tube 32` which is filledwith waterwhen in use.

Chlorin is admitted from the cylinder 2 through a flexible conduit 4l,which connects with a poit 42 in the cap 23, which in turn connects withthe pipe 34. By this means the chlorin enters pipe 34 and displaceswater in thebell shaped portion 36, the displacement being indicated bythe water level which liuctuates between the graduate marks 38.

As the lchlorin is under pressure, and a's the pressure balances withthat of the water in the surrounding tube 32, the chlorin escapes inbubbles through apertures 39, and rises in bubbles as indicated at 43,and finds its way through a port 44 in the rubber cork 33, whichregisters with a passage 46, terminating in the nipple 47 on the cap 23.The. chlorin is conducted from the nipple 4T through a flexible conduit48 to some remote point, for fumigation, insecticide operation, or inthe event that the apparatus is used for gopher exterminaton, theconduit 48 would be placed at the entrance of a gopher hole.

The cylinder 2 is provided with the usual control valve 5l, whichgoverns the dischargel of the chlorin.

The shell of the gage 18 is cut away on either side as indicated at 52,in order that the gage Amay be visible and the discharge of the chlorinwatched during the operation.

The gage is also provided with a sight bore 53, in which the Water levelis visible, it being understood thait the bores 53 and 52 are cut awayfrom both sides of the shell of the gage. i

Inasmuch as the gage is freely rotatable on the frame l, and theconduits are fiexible, the gage may be rotated on the frame to aposition best Suited to the light conditions for Watching the operation.

In operation, my device is carried into the iield, assembled-as shown inF ig. 1. It is raised from the ground a convenient distance and allowedto drop. The Weight ot the cylinder 2 forces the prongs 1T into theground, and the entire device is rigidly supported in an uprightposition. The gage is filled with water to the level indicated at insight port 53er if dry chlorin is desired I introduce in the place of'water in the glass tube 32 a body ol fluid which is repellent tochlorin, such as kerosene. rllhe valve 5l is opened and chlorin from thecontainer 2 enters tube 34, displacing water therein, and dischargesthrough ports 39, rising in bubbles through the water, and dischargesthrough flexible conduit 48 to the point at which it is to be used.
